FULLlNG-MILL.

SPECIFICATION forming part of Letters Patent No. 248,537, dated October 18, 1881.

' Application filed September 1, 1881. (Mode-l.) 7

To all whom it may concern:

Be it known that I, WILLIAM C. WARING, of Yonkers, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in Fulling-Mills, of

which the following is a specification, reference.

being had to the accompanyingdrawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of my improve ment, the side ofthefulling-box being removed. Fig. 2 is a plan view of the same, partly in horizontal section and part being broken away. Figs. 3 and 4 are side elevations ofthe crankwheels. l

The object of this invention is to promote convenience and economize expense in operating falling-mills.

The invention consists in the combination, with the shaft that operates the hinged liningplate and the cam-roller that operates the beater, of the crank-wheels and the connectingrod, whereby the said hinged lining-plate will be operated automatically from the said camroller, as will be hereinafter fully described.

A represents the fullingbox, the rear part oftheinterior of which is curved upon the arc of a circle having forits center the axis of the beaterB. TheforwardpartoftheboxAismadeupon a smaller curve and its upper part is extended inward to prevent the liquid contents of the box from spattering and the material being operated upon from beingforced out by the said heater. The rear part of the box A is lined with a metal plate, 0, to prevent the bottom from being worn by the beater. The forward part of the box A is lined with a metal plate, D, to preventit from being worn by the material being operated upon. The adjacent edges of the plates D O are hinged to each other to allow the upper part of the forward plate, D, to be moved inward to turn the material. The hinge E of the plates 0 D enters a recess in the bottom of the box A.

The beater B is curved upon the arc of a cirole, and has its forward end rabbeted to form a The beater B is attached to two bars, F, the outer ends of which are secured to a shaft or rod, G, which works in bearings in the upper ends of the arms or brackets H, formed upon or attached to the forward end of the box A. Theinner ends of the bars F project, and to and between them is hinged the lower end of the board or plate I, which passes up between two rollers, J K. The roller J revolvesin hearings in the upper ends of the arms or brackets L, attached to or formed upon the rear end of the box A.

To one journal of the roller J is attached a pulley, M, to I'l'CGiV'B the driving-belt. To the other journal of the roller J is attached a conepulley, N, around which passes a belt, 0. The belt 0 also passes around a cone-pulley, P, attached to a journal of the cam-roller, Q, the journals of which revolve in bearings in the lower parts of the brackets L.

To ajournal of the roller Jis attached a gearwheel, It, the teeth of which mesh into the teeth of the gear-wheel S, attached to ajournal of the roller K, so that the said roller K will be revolved from and by the roller J. The journals of the roller K revolve in bearings in the upper ends of the bars '1, which are fulcrume-d to lugs formed upon the brackets L. The lower ends of the bars T project nearly to the side of the cam-roller Q.

To the middle parts of the bars T are hinged the upper ends of the bars U. The lower parts of the bars T U are drawn toward each other by rubber or spiral springs or other suitable springs, V, attached to them, and are kept from being drawn too close together by stop-blocks W, interposed between them and attached to one or the other of the said bars.

To the lower ends of the bars U is pivoted a small roller, X, which bears against the side of the cam-roller Q. With this construction, when the roller X rests against the larger part of the cam-roller Q, the roller K will be forced toward the roller J, so that the board I will be clamped between the said rollers K J with so much force that it will be carried up by and between the rollers K J, raising the beater B.

As the roller X passes to the smaller part of the cam-roller Q the pressure of the roller K toward the roller J will be relaxed so much that the board I will be released and the beater B allowed to fall against the material in the fulling-box A.

To the upper edge of the forward lining plate, D, are hinged the ends of two connecting-rods, Y, the other ends of which are hinged to the outer ends of two arms, Z, formed upon or attached to the shaft a. The shafta works in bearings attached to the upper forward corners of the fulling-boxAor in the brackets H. With this construction, by turning the shaft a, the upper part of the lining-plate D will he swung inward so as to dislodge the material from the place into which it has been driven by the beater B and turn the said material over, so that it will be struck by the said heater B in a new place. This has heretofore been done by means of a crank attached to the end of the shaft a, and necessitated the employment of an attendant for that purpose.

In my improvement I replace the crank by a crank-wheel, b, to the crank-pin of which 1 pivot the end of a connecting-rod, c, the other end ofwhich is pivoted to the crank-pin of the crank-wheel (I, attached to thejournal ot' the cam roller Q, so that the lining-plate D will be operated automatically from the said cam-roller Q to turn the material. Several holes are formed in the crank-wheels b d to receive the crank-pins, so that the throw of the lining-plate D can he regulated, as required. The crank-pins of the crank-wheels b d should be so arranged that the revolution of the crankwheel d willonly'rock the crank-wheel b.

It'desired, the connecting-rod 0 can be formed of two rods having' screw-threads upon their ends to receive the nuts by which they are secured to the ends of cross-heads that are pivoted at their centers to the crank-pins of the crank-wheels b d.

The advantage of this construction is that it allows the connectingrod to be lengthened and shortened as the adjustment of the crank-pins may require.

This machine is especially intended for sizing for hats, but it can also be used for sizing and falling cloth.

Having thus fully described my invention, 1 claim as new and desire to secure by Letters Patent- In a falling-mill, the combination, with the WILLIAM G. WARING.
